Description

Hemodialysis pipe dropout prevention means

Technical Field

The utility model relates to a hemodialysis treatment auxiliary device field specifically is hemodialysis pipe dropout prevention means.

Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The blood and electrolyte solution with similar body concentration are arranged inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and the substance exchange is carried out through dispersion/convection, thereby removing the metabolic waste in the body and maintaining the balance of the electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis. The establishment and maintenance of a good vascular access for blood purification is the primary condition for ensuring smooth blood purification and adequate dialysis. Vascular access is also the "life line" of long-term maintenance hemodialysis patients. According to the requirements of the patient and the blood purification mode, the vascular access is divided into an arteriovenous fistula, a temporary central venous catheter and a central venous catheter with a terylene sleeve for clamping and protecting. The ideal vascular access has enough blood flow volume when blood permeates, is convenient to puncture, and is durable and has few complications. When designing the vascular access, the temporary vascular access or the permanent vascular access should be selected according to the primary cause of renal failure, the degree of reversibility, age, hospital conditions, and the like of the patient.

For the vascular access established by the hemodialysis catheter, on one hand, no special fixing device capable of reliably fixing the hemodialysis catheter exists, and common medical gauze or other medical adhesive tapes are usually used for clinically winding and fixing on the skin of a patient layer by layer. The thick and heavy wound medical gauze and the like not only cause the neck or the arm of the patient to move inconveniently, but also greatly increase the labor capacity of medical staff. And medical gauze or other medical adhesive tapes are adopted for winding and fixing, and the tube-removing rate of the patient is still up to 5-10% by clinical statistics. And when fixed catheters such as medical adhesive plaster are adopted, part of patients can generate allergic reaction to the adhesive, which is extremely unfavorable for the medical process, and the frequency of the activity of the patients can be increased after the patients generate allergic symptoms, so that the probability of tube detachment is increased, the hemodialysis catheter is an important life line of the patients, and once the tubes are detached, the hemodialysis catheter can cause extremely high economic burden and physical burden to the patients. Therefore, how to enhance the stability of the hemodialysis catheter fixed on the patient while protecting the patient from the excessive burden becomes a problem to be solved in the field of hemodialysis treatment auxiliary devices.

SUMMERY OF THE UTILITY MODEL
